All releases of Netcat 6

Release Notes: This release fixes a bug in the --half-close mode and introduces a --continuous option that keeps listening for new connections and a --exec option that executes a given command and binds its stdio to the connection. Used together, these two options can make the program work somewhat like inetd.

Release Notes: This release fixes a couple of bugs (parsing of --no-reuseaddr option and a weird bug that could generate an endless loop) and introduces two new features: idle timeouts and the --sndbuf-size and --rcvbuf-size options for setting SO_RCVBUF and SO_SNDBUF respectively.

Release Notes: This release introduces many new interesting features: accept/connect timeouts, hold timeouts, recv-only and send-only modes, half-close mode, high flexibility of use, i18n support, and enhanced UDP support. From this release nc6 uses, if present, the AI_ADDRCONFIG flag of getaddrinfo for the connect mode. Now file transfer mode works also with UDP. The configuration process and the whole architecture of nc6 have been greatly improved.
